1. Of a satellite, the projection of the orbital plane on the earth's
surface, the locus of the satellite subpoint.

Since the earth is turning under the satellite, the path of a single
orbital pass will not be a closed curve. Path and track are used
interchangeably. On a cylindrical map projection, the path is a sine-shaped
curve.

2. Of a meteor, the projection of the trajectory
on the celestial
sphere, as seen by the observer.
